This brief concluding chapter recaps the main conclusions of the body chapters, affirms the importance of cognitive theorizing for the study of ancient religion, locates the different religious expressions studied in these chapters along a continuum of cognitively optimal and costly religion, and points to potential areas of future research at the intersection of biblical studies, Israelite religion, and cognitive science of religion (CSR).

This chapter reframes the traditional dichotomy between popular and official religion and argues that ritual practices in both official and domestic settings were informed by intuitive conceptualizations of supernatural agency. As an alternative to popular and official religion, the categories cognitively optimal and cognitively costly religion are proposed as a fruitful framework for understanding the diversity of religious expression in ancient Israel. It is argued that from the standpoint of human cognition, ritual offerings performed in both popular and official contexts share deep structural features in common − whether in households, villages, local shrines, or state-sponsored temples. The final section of the chapter evaluates the recent shift to the study of family or household religion in ancient Israel. An analysis of material artifacts and religious ritual practices in domestic and official contexts reveals interesting points of continuity across these domains. Overall, a cognitive perspective suggests that the difference between home and temple, ancestors and the national deity, may not have been as great as it is sometimes imagined.

This chapter uses current theories in the cognitive science of religion (CSR) to examine the widespread popularity of hybrid monsters in ancient Syro-Palestinian and Near Eastern art and the role of material culture in enhancing memory and expanding the ordinary boundaries of the religious imagination. The chapter analyzes the iconography of hybrid figures from the perspective of two current cognitive frameworks: Dan Sperber’s epidemiological approach to cultural representations and Pascal Boyer’s theory of minimally counterintuitive (MCI) concepts. Artifacts and imagery include hybrid creatures on glyptic and minor art, monsters and demons, as well as a discussion of hybrid creatures such as the seraphim and cherubim in the biblical books of Isaiah and Ezekiel. It is argued that culturally specific depictions of hybrid animals exhibit a core set of properties, which helps to account for their stability across geographical and temporal distances. The MCI theory is also empirically tested with recourse to the ancient iconographic data.
